S. J. ANDERSON AND N. RICHARDSON, OF ERIEV ILLE, NEW YORK.

EXTENSION-CHAIR.

Specification of Letters Patent No. 16,635, dated February 17, 1857.

To all whom it may concern:

Be it known that we, S. J. ANDERSON and NELSON RICHARDSON, of Erieville,in the county of Madison and State of New York, have invented a new andImproved Extension-Chair; and we do hereby declare that the following isa full, clear, and exact description of the same, reference being had tothe annexed drawings, making a part of this specification, in which-Figure l, is an end view of our improvement. Fig. 2 is a longitudinalvertical section of ditto. Fig. 3, is a plan or top view of ditto.

Similar letters of reference indicate corresponding parts in the severalfigures.

Our invent-ion consist-s in att-aching a series of jointed leversprovided with legs, and also a series of folding seats to a box, andarranged as will be hereinafter fully shown and described, whereby, whennecessary, the levers may be extended or drawn out from the box and theseats unfolded and placed upon them, and the box also unfolded so that along bench is obtained, and when the long bench is not required thewhole may be inclosed within the box, which may then serve as awash-stand table or other piece of furniture.

To enable those skilled in the art t-o fully understand and constructour invention we will proceed to describe it.

A, represents an oblong rectangular box, which is divided longitudinallyinto two parts (a) (b) connected at one end by a hinge (c). Within thebox A a series of crossed jointed levers (CZ) are placed. These leversare constructed and arranged precisely similar to those used for similarpurposes. The manner in which they are jointed is clearly shown in redFig. 3. These levers are provided with legs (e) and the outer ends ofthe two innermost levers (cl) (d) are connected by a bolt (f) which hasa head on its upper end, said bolt tting between the upper surfaces ofthe two parts (a) A slot is made in the part (a) of the box A, the endopposite to that where the hinge c) is att-ached. This slot is shown bydot-ted lines in Fig. 3.

B represents a series of seats each of which is equal in length to thebox A, and nearly or quite equal in width to the part (a) of the box.These seats may be constructed of boards, or they may be constructed offrames having cane, rush, or other suitable bottoms formed in themsimilar to chair seats. These seats are connected at their ends byhinges (7L) so that they may be folded over each other and rest upon thepart (a) of the box A as shown in Figs. l and 2.

The end of the part (b) of the box A opposite to the end where the hinge(c) is attached has a door C, hinged` to it. This door covers the endsof the two parts (b) as shown in Fig. 1.

The top of the box A may be provided with a wash-stand top D, or asimple table top may be placed upon, or any other attachment may beapplied to it by which the box may be rendered serviceable when not usedas au extension chair.

When the levers (cl) are folded and inclosed by the box A, and the seatsB folded upon it the device is very compact occupying but a small space.The device is extended in the following manner. The door C is Opened,and the levers (d) are drawn out from it till the bolt (f) fits in theslot (g), and, if the greatest length of seat is required, the part (b)of the box A is turned around in line with the part The seats B are thenunfolded and placed on the levers (rl). The top D is of course removedwhen the device is extended.

The implement is simple, may be constructed at a moderate cost and thereare no parts liable to get out of repair.

Ve do not claim the levers (d) for they have been previously used forsimilar or lanalogous purposes, and are well known Having thus describedO-ur invention what we claim as new and desire to secure by LettersPatent, is-

The levers (d) and folding seats B, attached to the box A as shown, thebox being formed of two parts (a) (o) connected by a hinge (c) and thewhole arranged as described for the purpose set forth.
